Frost Quakes: Exploring a Rare Weather Phenomenon
An arctic blast is due to hit many countries around the world, and it could result in a rare weather phenomenon, Frost Quakes. Here we will take a look at what Frost Quakes are and why they occur.
What is a Frost Quake?
A Frost Quake, sometimes referred to as a cryoseism, is a form of seismic activity which can occur when extreme temperature drops cause the ground to freeze and expand suddenly. This pressure can cause a loud boom, and in some cases damage to the ground.
Where do Frost Quakes Happen?
Frost Quakes primarily occur in areas where the ground is particularly wet, such as rivers, marshes, and near lakes. They can also occur near valleys, ravines, and hills.
What Causes Frost Quakes?
Frost Quakes are caused by extreme cold temperatures. When these temperatures cause the ground to freeze, the water beneath the surface expands and contracts rapidly, causing seismic activity and a booming sound.
How Common are Frost Quakes?
While Frost Quakes can occur anywhere in the world with temperatures below freezing, they are relatively rare. However, with the upcoming arctic blast, we may see more Frost Quakes than usual across much of the globe.
What to Look Out For
If you’re in an area where there is a chance of a Frost Quake, here are some things to look out for:
- Noise: A loud booming or cracking sound is a sure sign of a Frost Quake.
- Harmful Structures: Frost Quakes can cause damage to buildings, roads, and other structures near rivers, ponds, and other bodies of water.
- Ground Movements: Frost Quakes can cause the ground to shake, so be aware of any strange vibrations.
Frost Quakes are a rare and fascinating weather phenomenon, and you may get the chance to witness one during this arctic blast. It pays to be prepared – and above all else, stay safe.
On January 16, 2020, much of Canada experienced a profound cold, with temperatures dipping as low as -30°C in some areas. This Arctic blast produced an astonishingly rare weather event known as a “frost quake.”
Frost quakes, also known as cryoseismic events, involve loud booms as the ground near the surface cracks due to sudden cooling and contraction of water, soil, or rock. These quakes occur when water at the ground surface freezes rapidly and expands, leading to the abrupt release of energy in the form of shock waves, or quakes.
Frost quakes may not be as intense as tectonic earthquakes, but can still be disorienting and startling to those who experience them. Reports of frost quakes after the recent cold snap ranged from thunder-like sounds to sonic booms.
Though frost quakes are usually harmless and brief, there is a possibility that they may cause structural damage and fracturing of walls, ceilings and foundations. As such, it is advisable for affected homeowners to inspect the structure for any lost or damaged components.
The most effective way to avoid frost quakes is to prevent surface water from freezing by using ground insulation, which helps to maintain warmth. It’s also important to seal any gaps around windows, doors and other openings to reduce the chances of a frost quake occurring.
Frost quakes may be rare and unexpected, but through preventive measures and awareness, individuals can minimize the risk posed by such an event.
